LOAD-BINDER.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed April 16,1906- Serial No. 312,064.

To all whom it may concern:

Be it known that I, GEORGE WILLIAM LEEPER, a citizen of the United States of America, residing at 210 East Forty-second street, in the city of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Load- Binders, of which the following is a specification.

This invention relates to a device for binding or tightening the'chain, rope or cable around an object or objects to be secured.

The object of the invention is to provide a simple and efficient device of this character which is cheap to manufacture and easy to operate.

In the accompanying drawings, Figure 1 represents an edge view of the binder; Fig. 2 represents a side elevation thereof partly in'section; and Fig. 3 represents a horizontal section taken on line 33 of Fig. 2.

In the form shown this binder which is preferably made of steel comprises a frame D constructed of spaced side members (I d connected at their lower end by a crossbar e which is preferably made integral therewith and at their upper ends by a slotted barf. The inner oppositely-disposed faces of these side members or bars (I d are provided with downturned hook-shaped ratchet teeth It having curved lower faces forming sockets H, the sockets on one side bar being arranged opposite the teeth on the other side bar. One of the side bars d has oppositely-extending flanges as D for a purpose to be described.

A lever C has a bifurcated end a mounted to slide 0 the frame D, the arms of said bifurcated lever end hav ing curved oppositely-disposed inclined slots as 0 arranged therein in which are loosely mounted rollers g g. These rollers have retaining heads g g and are adapted to engage the sockets H under the ratchet teeth h. The free ends of the arms of the bifurcated lever end 0 are rounded to engage the flanges D D and serve as a fulcrum when the lever is moved downward. A flexible element A is attached at one end between the arms of the bifurcated lever end 0 and at its other end is preferably provided with a hook A for engaging one end of a binding memberF. The cross-bar f is slotted to permit the flexible element A to pass freely therethrough and is preferably provided with rollers f to facilitate the movement of the element A therebetween.

Mounted on the end of the frame D having the crossbar a is a slotted bracket I in the slot of which is fulcrumed a bell-crank lever. The short arm B of this bell-crank lever is movable in the slot of the bracket and is adapted to be engaged by a pivoted trip member E to lock the binder in operative position. The binding element F is detachably connected at one end with the long arm of the bell-crank lever which is preferably bifurcated and in the form shown the binding element comprises a chain, one link of which is disposed between the arms B and B of said bifurcated long lever arm. The trip lever or arm E is limited in its movement by a keeper E and is preferably provided with an operating handle E In the use of this binder the lever C being placed near the bar f of the frame D and the flexible member A connected with the element F, said element F is drawn as tightly as possible around the article or articles to be bound by hand and the short arm B of the bell-crank lever is swung upward into the bracket and the trip lever E is dropped down in front thereof to hold it in this position. Then the lever G is raised and lowered like a pump handle and the rollers g, g dropped by force of gravity into the sockctsunder the teeth It until sufficient tension is applied to the articles to be bound To release the load, the trip lever E is raised and the tension on the, binding element will draw the bell-crank lever down and unfasten the binding element so that it may be removed.

I claim as my invention 1. In a load hinder, the combination of a member having ratchet teeth, a lever having slots in one end thereof, rollersslidably mounted in said slots to engage said teeth, a flexible element connected at one end to the slotted end of said lever, a beILcrank-lever mounted on said teeth carrying member, a binding element connected with one arm of said bell-crank lever and adapted to be connected with said flexible element and means for engaging the other arm of said bell-crank lever to hold it in operative position.

2. A load binder comprising a frame composed of spaced side bars having ratchet teeth on their inner faces, a lever having one end bifurcated to. straddle said side bars, rollers slidably mounted in said bifurcated lever end to engage said ratchet teeth, a binding element, a flexible element connected with said lever end, and a member pivotally mounted on said frame for engaging one end of said binding element, and means for locking said member to hold said binding element tight.

3. A load binder comprising a frame composed of spaced side bars having ratchet teeth on their inner faces, a lever having one end bifurcated to straddle said side bars, rollers loosely mounted in said bifurcated end to engage said ratchet teeth, a flexible element connected with said lever end, a binding element detachably connected with said flexible element, and a bell-crank lever fulcrumed to said frame and having means for detachably engaging the free end of said binding element and means for engaging said bell-crank lever to lock it in operative position.

4. A load binder comprising a frame composed of spaced side bars having ratchet teeth on their inner faces, a lever having one end bifurcated to straddle said side bars, rollers loosely mounted in said bifurcated end to engage said ratchet teeth, a flexible element connected with said lever end, a binding element detachably connected with said flexible element, a bell-crank lever fulcrumed on said frame and having one arm thereof bifurcated to receive the free end of said binding element and a trip lever or latch for engaging the other arm of said bell-crank lever to hold it in operative position.
